If you could somehow manage to buy every possible combination you'd win every possible prize. Besides the 5+1 winner you'd have all 25 5+0 winners. You'd have 320 4+1 winners, and at the end of the prize list you'd have 7,625,297 0+1 winners. All told you'd have 11,751,237 winning tickets worth just under $93.469 million, plus the jackpot winning ticket. In the case of a jackpot worth $1.586 billion and a 3-way split the jackpot ticket would be worth about $328 million in cash, bringing your total winnings to about $421 million.
Your actual winnings if you could have done it for the record would actually be significantly bigger. By spending $584.4 million buying tickets you'd have added nearly $200 million to the cash value of the jackpot, increasing the 1/3 share of the jackpot by about $65 million. That would mean you'd have won back about $485 million, for a loss of about $100 million. Except that buying all of the combinations would have made yours the 4th jackpot winning ticket. That would have resulted in actual winnings of about $388 million, for a loss of $200 million.
That last bit is a hugely important factor. If the jackpot is big enough that there's any chance at all of turning a profit you have to figure that there will probably be at least 1 winner from the regular players, and that the jackpot will be split at least 2 ways. In this case that would have resulted in winning almost $683 million, for an after tax profit of a bit less than $60 million. That's a very nice profit, but the high risk of a 3rd or 4th winner makes it a bet that I wouldn't expect anyone to take.
Maybe there's still an occasional state lottery where it would be a good bet if you could overcome the logistics and buy every combination, but short of a much bigger jackpot with sales that stabilize at the current maximum PB and MM will never be a good bet.
